Q:What kind of coke is needed for smelting special steel

It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnace

Q:The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?

80% to 90% of the sulfur in coal into coke, the other into the coke oven gas.

Q:What is the phosphorus content in coke

After drying, pyrolysis, melting, bonding, curing, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization)

Q:What is the use of petroleum coke

According to the quality can be divided into two kinds of primary and qualified products. Qualified products are divided into six grades. Used in the manufacture of electrodes, calcium carbide, corundum and so on and used as a filling tank, also used as insulating materials and fuel, etc..

Q:Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?

It is a solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure.

Q:How to distinguish the level of coke. What is metallurgical coke

Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Other more specific can see here:

Q:Who knows the proportion of pig iron and coke used in Cupola

There is doubt: the export rate is lower than the standard exception.4, blank blank processing: according to customer requirements of different direct sales, some need to continue processing after the sale, the ordinary rough machined after a blank rate of about more than 70%, about 30% (excluding scrap scrap), dryer enterprises after after machining yield is about 25% ~ 30% (including waste scrap and iron, basically use recycled material, material waste accounted for ratio of 30% ~ 40%). To 1.5M x 2M cylinder, for example, rough weight of about 5.8 tons ~ ~ 6 tons (standard cylinder, including the cylinder head) cylinder head rough weight of about 1.7 tons ~ ~ 1.8 tons, cylinder weight of about about 4.2 tons. After processing, the cylinder head weighs about 0.5 tons to 0.6 tons, accounting for the proportion of about 65% to 70% head (excluding scrap, scrap accounted for about 10%, blank cylinder head and iron) accounted for about 30% ~ 35% blank cylinder head, accounted for the proportion is about 40% recycled waste, scrap iron accounted for under foot material proportion 60%, enterprises can not return direct sales (currently, only production enterprises can use recycled scrap iron). Total iron blank ratio is about 15% ~ 18%.

Q:8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.

Ethylene containing carbon carbon double bond can add poly to generate polyvinyl chloride, can be used for food packaging, reaction equation is: nCH2=CH2Initiator,The answer is: nCH2=CH2Initiator;

Q:Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce

The role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.

Q:What are the national standards for grade two coke?

All of these are the main indicators, and the water is not the quality evaluation index. The other is the coke reactivity: no more than 35%; after the reaction intensity: not less than 50%
